I Suffer From Swollen And Irritated Eyelids. Prescription Drops For

I suffer from swollen and irritated eyelids. Prescription drops for dry eyes do not help and give me blurred vision. I do not use make-up and only special eye moisturising cream or gel for the area around my eyes, nothing perfumed. I had cataract surgery on both eyes 2 years ago and was given drops for dry eyes afterwards which seemed to be the beginning of my problems. I use preservative free drops.
